Abstract: In order to improve nitrogen management for higher yield and quality of strong gluten wheat, at N fertilizer application amount of 240 kg/hm², the effect of nitrogen dressing application on the yield and grain quality of ‘Xinmai26’ at 4 different stages were studied. The results showed that, the yield increased first and decreased later with delay of nitrogen dressing application. Dressing nitrogen in booting stage was proved to be the best for the yield and achieved the most ears and the highest grain weight and second-placed grains per spike. Nitrogen dressing in shooting stage gained the longest dough stabilization time and the highest farinograph parameters, nitrogen dressing in flowering period had the lowest yield and the worst quality. The water absorption and stabilization time of different ‘Xinmai26’ dough in 4 different nitrogen dressing application didn’t vary significantly. All the above results suggested that dressing nitrogen in booting stage should be the best treatment with high yield and good quality.
